  • the duct 7 defines an elongated chamber 8 having the shape of a rectangular cylinder and extending across the loom.
  • the upper surface 8a of the chamber 8 is bounded by a perforated plate having a high open area ratio, and the lower surface 8b of the chamber is provided with a large opening, and thus air is able to flow downward through the duct 7.
  • Each axial fan 6 has an impeller 9, and a motor 10 for rotating the impeller 9.
  • the axial fans 6a to 6n are arranged longitudinally at intervals in the chamber 8, to produce uniformly distributed air currents that flow across the chamber 8 to provide a suction force.
  • the endless filtering belt 2 is disposed in such a manner that the upper side thereof runs substantially in a horizontal plane along the upper wall of the duct 7, and the lower side thereof runs substantially in a horizontal plane along the lower wall of the duct 7.
  • the endless filtering belt 2 is extended between driving pulleys 4 with a built-in motor and tension pulleys 5.
  • the endless filtering belt 2, in general, is an endless wire mesh belt, but the endless filtering belt 2 may be formed of any other suitable material provided that the endless filtering belt 2 is capable of collecting flies.
  • Indicated at 3a and 3b in FIG. 1 are reinforcing bands for reinforcing the endless filtering belt 2, to lengthen the service life of the endless filtering belt 2.
  • the fly removing device 11 is disposed near one end of the endless filtering belt 2 on the side of the tension pulleys 5, to remove flies collected on the outer side 2a of the endless filtering belt 2 with a suction nozzle 11a by suction as the endless filtering belt 2 turns in the direction indicated by an arrow.
  • FIGS. 3 and 4 show the loom cleaning apparatus 1 incorporated into an air jet loom 12.
  • a number of warp yarns Y let off from a warp beam 13 are advanced via a back beam 14, drop wires 15, and heddles 16.
  • a weft yarn inserted in a shed formed by the heddles 16 is beaten with a reed, not shown, to weave a woven fabric F which, in turn, is rolled in a cloth roll 17 on a cloth roller.
  • the warp yarns Y pass the drop wires 15 and the heddles 16, the warp yarns Y are abraded by the drop wires 15 and the heddles 16 and rub against each other, to produce flies which fall down and are deposited on the floor under the loom. These flies deposited on the floor can be scattered by a draft and adhere to the warp yarns Y.
  • a space between the back beam 14 and the heddles 16 under the warp yarn Y is available for installing the loom cleaning apparatus 1.
  • the loom cleaning apparatus 1 produces downward air currents, and thus the loom cleaning apparatus 1 allows the air to flow downward, together with flies, therethrough as indicated by arrows in FIG. 3. Accordingly, the flies produced by the drop wires 15 and the heddles 16 are trapped by the endless filtering belt 2 of the loom cleaning apparatus 1, and the trapped flies are removed from the endless filtering belt 2, and thus a deposit of flies on the floor under the loom cleaning apparatus 1 does not occur.
  • FIGS. 5 and 6 show the loom cleaning apparatus 1 in second and third embodiments thereof according to the present invention, respectively.
  • the upper side 22a of the endless filtering belt moves along the upper surface 8a of the chamber 8 of the duct 7, and is guided by a deflecting device disposed on one end of the loom cleaning device 1 to move substantially in a vertical direction along the side surface 8c of the chamber 8, as indicated at 22b.
  • the portion 22b is guided by a deflecting device, not shown, disposed at the other end of the loom cleaning apparatus 1 to again move horizontally, and thus an open space is formed under the lower surface 8b of the chamber 8.
  • a deflecting device not shown
  • a diffuser 23 may be provided in the open space under the lower surface 8b, to reduce the amount of electric energy required for the operation of the axial fans 6, and as shown in FIG. 8, a nozzle 25 may be provided in the open space under the lower surface 8b to use air discharged from the loom cleaning apparatus 1 for cleaning the bottom portion of the loom.
  • a high-speed, high-performance loom has a compact construction, and thus only a very small space, compared with that in the conventional loom, is available between the warp beam and the heddles. Nevertheless, the compact construction, for example, 150 mm wide and 90 mm high in cross section, of the loom cleaning apparatus in accordance with the present invention makes it applicable to all kinds of looms.
  • a number of looms are installed in groups, and when all the looms are each equipped with the loom cleaning apparatus 1 of the present invention, collecting the flies accumulated in the fly removing devices 11 of the loom cleaning apparatus 1 from individual fly removing devices 11 is very difficult and thus impractical.
  • FIG. 7 shows an arrangement for facilitating the collection of the flies accumulated in the fly removing devices 11 of the loom cleaning apparatus 1 incorporated into a number of looms, in which the looms are represented by the loom cleaning apparatus 1.
  • the looms are divided into a group of looms 1aa, 1ab, 1ac, . . . a group of looms 1ba, 1bb, 1bc, . . . and a group of looms 1ca, 1cb, 1cc, . . . ; a group of fly removing devices 11aa, 11ab, 11ac, . . . , a group of fly removing devices 11ba, 11bb, 11bc, . . . , and a group of fly removing devices 11ca, 11cb, 11cc, . . . are connected respectively to branch ducts 31a, 31b, 31c, . . .
  • a controller 36 may be provided to open and close the on-off valves 35a, 35b, 35c, . . . sequentially one at a time, and to operate the loom cleaning apparatus when the on-off valve is open.
  • 37, 38a, 38b and 38c are signal lines connecting the on-off valves or the loom cleaning apparatus to the controller 36.
  • the operation for collecting the flies deposited on the endless filtering belts 2 of the loom cleaning apparatus of each group is performed intermittently.
  • the arrangement shown in FIG. 7 enables the use of a single fly gathering fan and a single fly stock bin for gathering the flies from the fly removing devices at all of the looms. Note, since the fly gathering operation is performed for each group of looms, the fly gathering fan may have a comparatively small capacity.
  • FIGS. 8, 9, and 10 show loom cleaning apparatuses as fourth, fifth, and sixth embodiments according to the present invention.
  • the loom cleaning apparatus 41 shown in FIG. 8 employs a fixed filter 42, and a scraping type moving fly removing device provided with a scraper 43.
  • the fly removing device travels along the upper surface of the filter 42, and the scraper 43 is supported at opposite end thereof by brackets 44 and each bracket 44 is reciprocated along a guide rail 47 by a belt driven by a scraper driving motor 45.
  • the scraper 43 scrapes off and gathers the flies deposited over the filter 42, and finally, discards the gathered flies into a fly collecting case 48.
  • the flies collected in the fly collecting case 48 are removed from the fly collecting case 48 through a fly gathering pipe 49.
  • the fly removing device shown in FIG. 1 disposed at one end of the endless filtering belt may be replaced by a scraping type fly removing device.
  • the loom cleaning apparatus 51 shown in FIG. 9 employs tangential fans 53 each provided with a motor 54, instead of the axial fans shown in FIG. 1.
  • the tangential fans 53 are arranged in a space between the upper and lower sides of the endless filtering belt 2 as shown in FIG. 9, and uniformly blow out air in a tangential direction.
  • Such a tangential fan is described in detail in, for example, Japanese Patent Publication (Kokoku) No. 01-25630.
  • the loom cleaning device 61 shown in FIG. 10 employs the tangential fans 53 and a scraping type fly removing device.
  • a loom cleaning apparatus constructed in accordance with the present invention collects, gathers, and removes flies produced at the loom, to prevent an adherence of the flies to the warp yarns. Since only the filter and the fans for producing air currents through the filter are provided as the principal components, the loom cleaning apparatus of the present invention can be installed in a comparatively narrow space under the upper components of the loom.
  • a central loom cleaning system of the present invention enables flies to be gathered from a plurality of looms by using a single fly gathering fan having a comparatively small capacity, and a single fly stock bin connected to the fly gathering fan, which reduces equipment and power costs and reduces the labor needed for the disposal of the gathered flies.
